TSP: Fix GCC 11.0.0 compilation error.

TSP: Fix GCC 11.0.0 compilation error.

This patch fixes the following compilation error
reported by aarch64-none-elf-gcc 11.0.0:

bl32/tsp/tsp_main.c: In function 'tsp_smc_handler':
bl32/tsp/tsp_main.c:393:9: error: 'tsp_get_magic'

bl32/tsp/tsp_private.h:64:6: note: in a call to function 'tsp_get_magic'

by changing declaration of tsp_get_magic function from
void tsp_get_magic(uint64_t args[4]);
to
uint128_t tsp_get_magic(void);
which returns arguments directly in x0 and x1 registers.

In bl32\tsp\tsp_main.c the current tsp_smc_handler()
implementation calls tsp_get_magic(service_args);
, where service_args array is declared as
uint64_t service_args[2];
and tsp_get_magic() in bl32\tsp\aarch64\tsp_request.S
copies only 2 registers in output buffer:
/* Store returned arguments to the array */
stp x0, x1, [x4, #0]

zynqmp: pm: Filter errors related to clock gate permissions

Linux clock framework cannot properly deal with these errors. When the
error is related to the lack of permissions to control the clock we
filter the error and report the success to linux. Before recent changes
in clock framework across the stack, this was done in the PMU-FW as a
workaround. Since the PMU-FW now handles clocks and the permissions to
control them using general principles rather than workarounds, it can
no longer distinguish such exceptions and it has to return no-access
error.

Use constant stack size with RECLAIM_INIT_CODE

Currently, when RECLAIM_INIT_CODE is set, the

Use constant stack size with RECLAIM_INIT_CODE

Currently, when RECLAIM_INIT_CODE is set, the
stacks are scaled to ensure that the entirety
of the init section can be reclaimed as stack.

This causes an issue in lib/psci/aarch64/psci_helpers.S,
where the stack size is used for cache operations in
psci_do_pwrdown_cache_maintenance(). If the stacks
are scaled, then the PSCI code may fail to invalidate
some of the stack memory before power down.

Resizing stacks is also not good for stability in general,
since code that works with a small number of cores may
overflow the stack when the number of cores is increased.

Change to make every stack be PLATFORM_STACK_SIZE big,
and allow the total stack to be smaller than the
init section.

Any pages of the init section not reclaimed as
stack will be set to read-only and execute-never,
for security.
